As a result, planorbids are able to breathe oxygen more efficiently than other molluscs. Indeed, formerly planorbids were thought to have dextral shells, and so species of this family were figured as if they had dextral shells. Prosobranch snails have a long incurrent siphon (tube) that draws water into the mantle (the tissue connecting the body to the shell), where gills extract oxygen. This is especially apparent in albino animals. Planorbidae, common name the ramshorn snails or ram's horn snails, is a family of air-breathing freshwater snails, aquatic pulmonate gastropod molluscs. The genus Camptoceratops Wenz, 1923 is no longer considered to be a planorbid. This is a convenience for understanding the shell, but is the opposite of the way the shell is actually carried in life.

Orb-weaving spiders are three-clawed builders of flat webs with sticky spiral capture silk. The snail is an aquatic gastropod, but it only lives in freshwater. Although it is now understood that these species are sinistral in shell coiling, disk-like Planorbid shells are often still shown in illustrations oriented as if they were dextral. Terrestrial snails are one of the most diverse groups of animals alive today, both in terms of their variety of form and the sheer number of species that exist. Unlike most molluscs, the blood of ram's horn snails contains iron-based hemoglobin instead of copper-based hemocyanin. Most people know a snail when they see one, but it is less common to be able to tell the difference between the two main types of aquatic snails.

Janssen, 092507). (1967). Those planorbid species which have a high-spired shell may have a narrow umbilicus, but frequently this is covered by callus.

(2007)[4] analyzed a limited number of genera of Planorbidae, based on sequences of mitochondrial 18S ribosomal DNA and cytochrome-c oxidase I (COI) genes, and on the basis of the results, they rearranged the taxonomy like this: "A-clade" sensu Albrecht et al.
